Step 1: Create Infrastructure and Plan

Creating the DuploCloud Infrastructure and a Plan

Each DuploCloud Infrastructure is a connection to a unique Virtual Private Cloud (VPC) network that resides in a region that can host Kubernetes clusters. An Infrastructure can reside On-Premises (On-Prem) or in a Public Cloud.

After you supply a few basic inputs, DuploCloud creates an Infrastructure for you within Azure. Behind the scenes, DuploCloud does a lot with what little you supply—generating subnets, NAT gateway, routes, and a cluster in the region.

With the Infrastructure as your foundation, you can customize an extensible, versatile Platform Engineering development environment by adding Tenants, Hosts, Services, and more.

Estimated time to complete Step 1: 40 minutes. Much of this time is consumed by DuploCloud's creation of the Infrastructure and enabling your AKS cluster with Kubernetes.

Prerequisites

Before starting this tutorial:

• Learn more about DuploCloud Infrastructures, Plans, and Tenants.

• Reference the Access Control documentation to create User IDs with the Administrator role. In order to perform the tasks in this tutorial, you must have Administrator privileges.

Creating a DuploCloud Infrastructure

1. In the DuploCloud Portal, navigate to Administrator -> Infrastructure.

2. Click Add. The Add Infrastructure page displays.

3. From the table below, enter the values that correspond to the fields on the Add Infrastructure page. Accept all other default values for fields not specified.

4. Click Create to create the Infrastructure. It may take up to half an hour to create the Infrastructure. When creation completes, a status of Complete displays.

Add Infrastructure page field	Value
Name	nonprod
Subscription	YOUR_AZURE_SUBSCRIPTION_NAME
VNET CIDR	10.23.0.0/16
Subnet CIDR	10.23.0.0/20
Cloud	Azure
Region	YOUR_GEOGRAPHIC_REGION

Infrastructure creation with a status of Complete

Enabling Kubernetes for Azure

1. In the DuploCloud Portal, navigate to Administrator -> Infrastructure.

2. Select the nonprod Infrastructure you created.

3. Click the Kubernetes tab.

4. Select the Click Here link. The Configure AKS Cluster pane displays.

5. Enter a name in the Cluster name field.

6. Select the node VM size from Node VM Size list box.

7. To use Windows containers, Network plugin should be set to Azure. This config will make Kubernetes pods to get IP assigned from Subnets address space, Make sure Infrastructure default subnet use /18 for network prefix. At least /20 should be used or IP Address space might run out.

8. Click Create. It may take some time to configure the cluster. The Kubernetes card on the Infrastructure page shows Enabled when the cluster is complete. You can also monitor progress using the Kubernetes tab.

Checking Your Work

Verifying a Plan Exists

Every DuploCloud Infrastructure generates a Plan. Plans are sets of templates that are used to configure the Tenants or workspaces, in your Infrastructure. You will set up Tenants in the next tutorial step.

Before proceeding, confirm that a Plan exists that corresponds to your newly created Infrastructure.

1. In the DuploCloud Portal, navigate to Administrator -> Plans. The Plans page displays.

2. Verify that a Plan exists with the name NONPROD, the name that you gave to the Infrastructure you created.

DuploCloud begins creating and configuring an AKS cluster using Kubernetes. You receive an alert message when the Infrastructure has been updated.

Verifying AKS is Enabled

You previously verified that your Infrastructure and Plan were created. Now, verify that AKS is Enabled before proceeding to Create a Tenant.

From the Infrastructure page, select the Infrastructure (NONPROD) that you created. When AKS has been Enabled, details are listed in the Kubernetes tab on the Infrastructure page. This page also displays the Enabled status on the Kubernetes card.
